Sailboat Sinks Off Treasure Island

THIS STORY WAS UPDATED AT 2:40 p.m.

A sailboat sank off Treasure Island over the weekend, according to reports from the Coast Guard. 

John Boggs, one of our readers, said he saw a sunken ketch off the east side of Treasure Island on Sunday. "Just the masts sticking up — none of the hull showing," Boggs wrote us on Facebook.

The Coast Guard confirmed that over the weekend, a sailing vessel was rapidly taking on water one mile north of the Bay Bridge and east of Treasure Island, with three people on board (the boat’s size and make were not identified).

Vessel Assist was called to the scene and attempted to dewater the boat. All persons were removed, as Vessel Assist tried to tow the boat to shore — but it sank in 25 feet of water. The vessel was not in a "sensitive site," and a diving company was contracted to raise the boat this week, according to a report from he Coast Guard.

Since we posted this story at noon today, we’ve gotten a few responses about the wreck:

"We passed it motoring home to Tiburon Yacht Club from the Encinal Yacht Club race Saturday evening. We circled it while calling the Coast Guard — they sent a boat out to mark it with a light. We might have hit it if it was not still light out."

And Colin Stewart took a video on the water, which was broadcast on KRON 4:
